If you look at the Dropbox embedder API page here (screenshot attached):
https://www.dropbox.com/developers/embedder
Scroll about 70% down the page, below the JavaScript code you should see a shared folder, instead you see a "Something went wrong" error
I am seeing this on my page where I am trying to embed a folder, and I am sure many others are seeing it on theirs if it is happening on Dropbox's site.
in the Console log it shows a 400 error, and the page referenced throws this message
Error in call to API function "trello/get_shared_link_metadata/batch": Unknown API function: /2/trello/get_shared_link_metadata/batch
